APPARATUS FOR CLEANING CATCH BASINS AND THE LIKE.

Application filed June 19,

T all whom it may concern:

Be it known that I, GEORGE WV. OTTERSON,

a citizen of the United States, and resident of Seattle, in the countyof King and State of Washington, have invented a new and usefulApparatus for Cleaning Catch Basins and the like, of which the followingis a specification.

The invention relates to traveling apparatus for cleaning catch-basinsand the like, such as that disclosed in my Reissue Patent No. 14,234,Dec. 19, 1916. The object of the present invention is to provide asimplified form of the vehicle tank-body set- 16 tling-bed forming apart of such apparatus.

Previously the baffle partitions were disposed transversely of thetiltable reardumping tank and were hung swingingly so that the separatedsolids could pass out beneath them. In the present instance the battlesare placed longitudinally so as to form lengthwise settling chambersfrom which the material can escape in dumping without movement of thepartitions; at the same time the organization is such that a circuitousflow is compelled from the inlet from the discharge line to the outletto the pump which operates the ejector.

In the drawings forming a part hereof:

Fig. 1 is a side elevation of an apparatus embodying the invention, thesettling-bed 'bein shown partly in side elevation and part y in section,and broken lines being used to show it partly tilted; and

Fig. 2 is a plan view.

The motor-vehicle 1 has a rectangular tank-body 2, its interior open tothe pressure of the atmosphere, a pump 3 adapted to be driven from theengine of the vehicle by connections, not shown, and a hydraulic ejector4 connected with the outlet of the pump and adapted to draw in and raisethe contents of the catch-basins and cause their delivery into thesettling-bed. The ejector 4 is adapted to be lowered into and raisedfrom the basins, and has a suitable flexible pressure line 5 forming theconnection between the outlet of the pump and the ejector-jet nozzle(not shown), and a flexible or telescopic discharge line 6 terminatingin a suitable nozzle 7 projecting over the top of the settling-bed. Aninlet line to thenpump is marked 8, the same load ing from a clear-wateroutlet 9 at one of 1919. Serial No. 305,239.

the lower forward corner regionsof the settl ng-bed.' A separable,automatically maklng and breaklng connection 10 between said outlet andthe inlet end of the line 8 I is provided as disclosed in priorapplications. The nozzle 7 of the discharge line is adapted to deliverthe mixed stream of water and solids into the other forward cor-v nerregion of the tank. ratus, with the tank in normal position, the ejectorlet down into a basin and the pump in operation, water is withdrawn fromthe settling-bed, wherein a supply is kept while the machine is upon itsrounds, forced by the pump downward to the ejector, where the ejectorjet is created, drawing in the contents of the basin through the intake11 and forcing them upward to the settling bed on the vehicle, where theliquid is separated from the solids and continuously used. to supply thepump and jet. When the cleaning is completed, excess water is run backinto the basin through a line 12.

The tank body is pivoted toward the rear upon the vehicle frame, asindicated at 13, and suitable hoisting means 14 is provided for raisingits forward end in order to discharge the accumulated material at theback. A tight tail-gate 15 hinged at the top is untastened and swingsrearward in this operation.

The interior of the tank contains a plurality of vertical baffles 16, 1616 interrupting the flow of the water from the inlet from the dischargeline to the clear-water outlet 9, causing it to pass in a circuitousmanner so that the two regions are remote in point of flow. The numberof these partitions may be varied, but it is characteristic of thepresent improvements that they extend longitudinally of thesettling-bed, that is to say, fore and aft of the vehicle, and are ormay be fixed. Flow openings 17, 17 17 are formed in their upper parts,alternately at front and rear, the baffle 16 nearest the inlet from thedischarge line having its opening at the rear, and the open- In such an.appa ing in the last partition being likewise at the outward andconsequently their solids pass out freely when the tank is tilted fordumping.

What I claim as new is:

1. In traveling apparatus for cleaning catch-basins and the like, asettling-bed comprising a vehicle tank-body tiltahle for rear dumpingand having longitudinal battles forming lengthwise settling-chan'ihers.

2. In traveling apparatus for cleaning catch-basins and the like, asettling-bed comprising a reardumping vehicle tank-body divided intolengthwise communicating settling-chambers, with flow openingsalternately at front and rear of the battles.

3. A settling bed comprising a tank-body tiltahly mounted on a vehiclefor rear clumping and having a tight tail-gate, and equipped withlongitudinal partition means provided with flow openings and dividingreassess the interior into lengthwise unobstructed settling chamberswhereby the solids are retained and are freely discharged through thetail-gate opening when the settling-bed is tilted on its support. I

4. A traveling apparatus for cleaning catch-basins and the like,comprising a vehicle, a tiltalole rear-dumplng tank-body thereon, a pumphaving a clear-water inlet connection from the tank, a hydraulic ejectorconnected with the outlet of the pump and a discharge line fordelivering back into the tank, characterized by longitudinal bafiies inthe tank forming a series of lengthwise compartments with circuitouscommunication, the outlet to the pump and the inlet from the dischargeline being in laterally remote compartments.
